Presumably contaminated intravenous infusion-induced Aspergillus terreus endogenous endophthalmitis presenting with posterior hypopyon.

A 36-year-old immunocompetent man developed endogenous endophthalmitis 1 week after intravenous fluid infusion in a rural setting. Large submacular abscess with posterior hypopyon warranted urgent vitrectomy which revealed Aspergillus terreus on fungal culture. Intravitreal and oral antifungals lead to resolution of inflammation with satisfactory anatomic outcome but poor visual outcome due to submacular scar.
